    If we put down dimension next week. Will this last us through the duration of the crabgrass germination period. Ultimate question is how long does dimension last for?

    A lot of factors will determine how long your control window will be. The rate at which it has been applied, rainfall amounts, microbial activity in the soil, etc.

    Having said that, I prefer Barricade over Dimension, because under most circumstances, Barricade will retain it's effectiveness longer than Dimension will. It's also kinder to the root systems of your lawns than Dimension is.

    Dimension will last 8 weeks tops.(look up it's soil half life) Around E. PA you will need you do a split app. if you choose Dimension.

    This year it's Barricade @ the 4 month control rate, goin down late april this year.

    If you are doing a grub control June/July then the Barricade is a better option. If you are not doing an insect control in June/July, you could make your 2nd Dimension app. in June, have Great Crab control, AND have Turfgrass seed come up in Sept. if needed.
